Sometimes I also wish to be able to introduce new operators.
Unfortunately, they are fixed in SPAD as well as in Aldor.
If I am allowed to dream then I would like to be able to write something
like
(x: A) \oplus (y: A): A == ...
(with \oplus being the actual (unicode) character for that operator).
Of course that raises lots of questions and I am not 100% sure whether
it would be a good idea to
1) allow unicode in identifiers
2) being able as a user to introduce new infix/postfix operators with
assigned precedences
